== Kernel ==
== Progress ==


The old kernel functions 52 and 53 have been removed and the [[New_network_api]] has been created.
System functions 52, 53 have been replaced by functions 74 (Network hardware access), 75 (BSD sockets) and 76 (Network settings and statistics). ''See sysfuncs.txt for details. <br />
Internally, the network stack has been completely rewritten (mostly from scratch).<br />
All network drivers have been converted and or rewritten to operate with the new network stack.<br />

I would really appreciate it if somebody could write some network applications,<br>
== We need your help! ==
So I can concentrate on kernel code now :),<br>

This page describes the development of the new network stack for KolibriOS
Since SVN #3556, the code has been merged in trunk and is now available in the english, russian spanish and italian builds of kolibrios!
You can find the latest source code on svn://kolibrios.org/kernel/trunk (websvn)
You can download an image file with pre-compiled library, applications, kernel and drivers on the builds page
All bugs may be reported to KolibriOS bug tracker

Progress

System functions 52, 53 have been replaced by functions 74 (Network hardware access), 75 (BSD sockets) and 76 (Network settings and statistics). See sysfuncs.txt for details.
Internally, the network stack has been completely rewritten (mostly from scratch).
All network drivers have been converted and or rewritten to operate with the new network stack.

  • Working
    • Attaching multiple network drivers/devices to the kernel
    • Sending and receiving Ethernet/IPv4/UDP/ICMP/ARP/TCP packets
    • Queuing of packets when necessary
    • UDP/TCP/RAW(ICMP/IP..) sockets (POSIX compatible)
    • Blocking sockets
    • IPC/local sockets (needs testing)
    • Dedicated network buffers (NET_buff_alloc, NET_buff_free)
    • IP address assignment for all network interfaces
  • TODO
    • Link detection for all network drivers (Currently works on RTL8139, RTL8169, forcedeth, mtd80x, i8254x)
    • Improved routing
    • TCP: reassembly queue, testing (timestamps, RTT, PAWS, ...), ...
    • PPP (need help developing/testing)

Drivers

In net-branch, the network drivers are external drivers, as described in Writing_drivers_for_KolibriOS.

The specifications of the new network drivers can be found in the article Writing_network_drivers_for_KolibriOS.

Currently supported network hardware

Unsupported PCI card? If you have a PCI/PCI-X/PCI-express ethernet card which is not listed above, and would like to acces the internet in KolibriOS, you may send me the card, and I'll send you one back that is already supported.

TFTPc

Tftpc.gif

VNCclient

This program allows you to control a remote computer. The remote computer must be running a VNC server that support the RFB 3.3 protocol.
The client currently supports RAW, CopyRect, RRE and TRLE encodings.
Authentication to a password protected VNC server is possible through the "VNC Authentication" algorithm.
There is currently no support for encryption.
TODO: ZRLE, ..

Zeroconf

This program reads settings from network.ini and configures the tcp/ip stack accordingly
You may choose for a manual setup, or dhcp / link-local.
TODO: keep listening for DHCP release packets etc.

NetSurf

Under construction
TODO: Improve front-end, ...

SocketDBG

Program that can be used for printing socket variables, usefull for debugging.

PPPoE

PPPoE dialer - unfinished

TCPserv

TCP server demo program, this program can be used with iperf client to measure performance of the stack.

Libraries

network.obj

Network library for KolibriOS, written by Clevermouse. Primary functions are getaddrinfo, inet_ntoa.

http.obj

HTTP client library, can be used to fetch content from the web.
Currently support HTTP/1.1 GET, POST and HEAD methods. HTTP proxy's are also supported (settings in network.ini).

Applications, old vs new
